I'd like to hook this DSL modem (bridged mode) to Airport Extreme Base Station (DHCP and NAT) to share my Internet connection. The IP address of the modem is 192.168.1.1; will I be able to share my connection "out-of-the-box", just plugging modem to Airport, or should I change the modem IP address?
Second question: I'm going to buy a Siemens S450IP VOIP telephone and I have to change its address from 192.168.2.x (default) to 192.168.1.x to match my LAN addresses. I am going to assign a static IP address such as:
IP: 192.168.1.4
Subnet mask: 255.255.255.0
Gateway: ??
What gateway address shoud I use? 192.168.1.1 (ADSL modem) or 192.168.1.2 (Airport Extreme)?
